IMPROVEMENT IN LUBRICATORS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 138,343, dated April:29, 1873; application filed March 1, 1873.

To all whom it may concern:

Be it known that I, WILLIAM B. PATTER- soN, of Chicago, in the county of(look and State of Illinois, have invented a new and Improved Oiler forSteam-Engines, of which the following is a specification:

gage and waste-cocks for letting 0d the steam pressure and condensedsteam, all arranged in such manner that the steam being admitted to theoil in the tank, and the feedcock opened at the bottom, the oil willflow into the steam-pipe with the current of steam when the engine isrunning, and be conducted along with the steam into the engine, but willbe prevented from escaping through the feedcock when the engine stops,because the pressure on the oil is then equal below to that above, andthe small passage in the feed-cock through which it passes will besufficiently obstructed thereby to prevent the oilfrom descendin g bygravitation.

Figure l is partly a side elevation and partly a sectional elevation ofmy improved oiler. Fig. 2 is a section on the line as w of Fig. 1. Fig.3 is a side elevation of the feed-regulating-valve 5 and Fig. 4 is ahorizontal section of Fig. 3 on the line y y.

A represents the oil-tank; B, the steampipe through which the steampasses from the boiler to the engine, and to whichthe tank is connectedat the top by a pipe, 0 D, and at the bottom by a pipe, E F, having acock, H. The latter, also, has a feed-cock, I, whose valve, K, hasa'groove, L, through it proportioned in size to the size of the engineto be lubricated, and through which the oil flows when the cock isclosed. M is a filling-pipe at the top, with a cup, N, at its upper endto receive the oil from the can; also, a stop-cock, O, to close it, andalso a pet-cock, P, for let ting oft the steam-pressure when the tank isto be filled. Q, is a glass gage connected to the pipes O and E, to showthe height of the oil in the tank. R is a pet-cock at the bottom, to letoft the water of condensation and blow out the settlings.

The cocks H and G will be closed and the cock 0 opened when the tank isto be filled. In case the steam-pipe has branches leading to severalengines, the oiler will be placed above the branches, so that the steamfor all the engines will be charged alike with the oil. The valve K ofthe feed-cock can be screwed off the seat from time to time to allow anymatters collected in it, so as to choke it up, to escape.

The oil-tank has a concave side, S, fitting against the side of thesteam-pipes, so as to have a broad seat thereon, and so that it will beheated in cold weather to prevent the oil or tallow from solidifying.

The operation is as follows: The cocks H i and G are shut off to breakthe communication with the steam-pipe B, while the cock 0 is opened toallow the inlet of oil from cup N. The oil then passes through pipe M,and is allowed to fill the reservoir A tothe extent required. The cock 0being now closed and the cooks G H opened, the steam rushes throughpipes D (J, and presses on top of the oil, while it also rushes inthrough pipe F, and presses against the oil coming through the channelsL. The pressure of steam being thus counterbalanced, the gravity of thelubricant alone regulates the flow, which is slow and regular. The oilis thus taken up as it comes through channels L, is mixed with thesteam, and performs its functions uniformly and economically.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent An oil-tank, A, connected to the steam pipes by thepipes (l D and E F, and provided with a feed-cock, I, a filling-tube, M,and the pet-cocks P It, and the connecting-pipes, having stop-cocks G H,all substantially as specified.
